Apple has advised its users that they should upload multiple antivirus software solutions on their machines to protect from possible infection.

As per the news reports, it is still not clear why Apple has given this advice to its users. But there are possibilities of new viruses circulating on the web and targeting the Apple operating system.

According to Apple, unlike Windows PCs, Mac has remained protected from mass malicious software primarily due to the availability of Unix base of Mac OS X operating system. Moreover, virus writers have mainly focused their attacks on Windows PCs, but now it seems that they are shifting their attacks to Mac.
